Description

Auxiliary absorbent article

The present invention relates to auxiliary absorbent articles that are mainly attached to disposable diapers.

Auxiliary absorbent articles (inner pads) that are used in layers on the inner surface of disposable diapers (hereinafter simply referred to as diapers) are known. The inner pad is provided with fastening tapes near the front and rear ends of the outer surface thereof for fixing the inner pad at a predetermined position on the inner surface of the diaper. The fastening tape is formed of, for example, a member on the male side of a hook-and-loop fastener that engages with the nonwoven fabric that is the inner sheet of the diaper (see, for example, Patent Documents 1, 2, and 3).

JP 2011-072451 A Japanese Patent No. 5134391 JP 2007-190178 A

When the diaper with the inner pad attached is a pants type, when the wearer excretes in the toilet or changes the inner pad, the diaper is lowered to below the knee, and after that, the diaper is pulled up to the original wearing position. When the diaper is pulled up, for example, the rear upper edge of the inner pad is pulled up while touching the buttocks, so that the upper end of the inner pad is bent toward the buttocks and rolled up between the buttocks. That is, the upper end portion of the inner pad is turned inside out so that the outer surface, which should face the inner surface of the diaper, contacts the buttocks side.

Then, the diaper is pulled up while the turned-up upper end of the inner pad is in contact with the buttocks side, so that the area where the diaper is caught on the buttocks side is expanded, the fixing tape of the inner pad is peeled off from the inner surface of the diaper, and the back of the inner pad is removed. The side can be partially turned inside out.

In this way, when the inner pad is partially turned over, the original absorption performance of the inner pad cannot be fully exhibited.

The present invention has been devised in view of the above circumstances, and provides an auxiliary absorbent article that can prevent or suppress changes in the wearing state of a pants-type disposable diaper even when it comes into contact with the wearer's body. intended to

The present invention is an auxiliary absorbent article in which a top sheet, an absorbent body, and a back sheet are laminated, and which is used by being worn on the inner surface side of a pants-type disposable diaper, wherein the auxiliary absorbent article is at least on the back side of the wearer in the longitudinal direction. In the region corresponding to the above, the pants-type disposable diaper provided in the region with relatively high rigidity on the boundary line from the end of the dorsal side to the region with relatively high rigidity against bending. The auxiliary absorbent article is arranged so that the edges of the fastening members to be worn are aligned.

According to the auxiliary absorbent article according to the present invention, it is possible to prevent or suppress changes in the wearing state of the pants-type disposable diaper even if it comes into contact with the body when worn.

FIG. 1 is a schematic diagram showing a state in which a wearer 300 is wearing an underpants-type disposable diaper 200 with an inner pad 100 attached (hereinafter referred to as underpants-type diaper 200), and FIG. 2 is a plan view of the inner pad 100 attached to the pants-type diaper 200 shown, viewed from the back sheet 12 (outer sheet closest to the top sheet (innermost sheet) 210 of the pants-type diaper 200). 3 is a cross-sectional view taken along line AA of FIG. 2. FIG.

<Configuration>
The illustrated inner pad 100 is one embodiment of an auxiliary absorbent article according to the present invention. The inner pad 100 is used in a state of being stacked in the thickness direction of the underpants-type diaper 200, as shown in FIG. Specifically, the inner pad 100 is placed over the inner sheet (top sheet 210 ) of the pants-type diaper 200 that is closest to the skin of the wearer 300 . The inner pad 100 can be applied as, for example, a urine absorption pad or a soft feces pad.

As shown in FIG. 2 , one side of the inner pad 100 in the longitudinal direction L corresponds to the abdomen of the wearer 300 and the other side corresponds to the dorsal side of the wearer 300 . As shown in FIG. 3, the inner pad 100 is formed by laminating a top sheet 11, an absorbent body 13, and a back sheet 12 in this order in the thickness direction. The top sheet 11 is the inner sheet closest to the wearer's 300 skin, and the back sheet 12 is the outer sheet furthest from the wearer's skin.

At least parts of the top sheet 11 and the absorbent body 13, and the absorbent body 13 and the back sheet 12 are bonded together by a bonding agent such as hot melt, so that the inner pad 100 is integrated.

In addition, the inner pad 100 may further include a second sheet between the top sheet 11 and the absorbent body 13 . The top sheet 11 and the second sheet are made of hydrophilic nonwoven fabric, and the back sheet 12 is made of a hydrophobic sheet. The absorbent body 13 absorbs moisture transferred through the top sheet 11 and the second sheet.

As shown in FIG. 2, the top sheet 11 and the back sheet 12 are formed to be slightly larger than the absorbent body 13 in plan view, and each have a peripheral portion that spreads outward from the outer peripheral edge of the absorbent body 13. are doing. The peripheral portion of the top sheet 11 and the peripheral portion of the back sheet 12 are bonded with a bonding agent such as hot melt.

Therefore, the top sheet 11 and the back sheet 12 are joined together and the absorber 13 is not provided in the peripheral portion. Of the peripheral portions, the ventral portion in the longitudinal direction L of the inner pad 100 shown in FIG.

In the inner pad 100, the absorber 13 is arranged between the top sheet 11 and the back sheet 12 in a region (inner region 23) inside the surrounding portion.

On the back sheet 12 of the inner pad 100, as shown in FIG. The fastening tape 50 attaches the inner pad 100 to the pants-type diaper 200 . The fastening tape 50 is formed of, for example, a hook member of a hook-and-loop fastener. The hook member of the fastening tape 50 is engaged with the nonwoven fabric of the top sheet 210 , so that the fastening tape 50 is joined to the top sheet 210 and the inner pad 100 is attached to the pants-type diaper 200 .

Since the fastening tape 50 can be attached anywhere on the top sheet 210, the mounting position of the inner pad 100 in the front-rear direction of the pants-type diaper 200 can be adjusted according to the physique of the wearer 300. .

As shown in FIG. 2, the fastening tape 50 is provided between the top sheet 11 and the back sheet 12 instead of the ventral side edge 21 and the dorsal side edge 22 formed only by the top sheet 11 and the back sheet 12. is fixed to the backsheet 12 in the inner region 23 in which the absorbent body 13 is arranged.

Moreover, the fastening tape 50 is arranged such that the edge 51 on the side closer to the ventral end 21 in the longitudinal direction L is along the boundary line L1 between the ventral end 21 and the inner region 23, , the edge 51 on the side closer to the dorsal end 22 is arranged along the boundary line L1 between the dorsal end 22 and the inner region 23 .

Here, since the inner region 23 is formed by the top sheet 11, the absorbent body 13, and the back sheet 12, the ventral side end portion 21 and the dorsal side formed only by the top sheet 11 and the back sheet 12 are formed. Compared to the end portion 22, it has a higher rigidity against bending. That is, each boundary line L1 between the inner region 23 and the ventral end portion 21 and the dorsal end portion 22 is a boundary line where the rigidity against bending is switched.

FIG. 4 is a schematic diagram showing the inner pad 100 attached to the pants-type diaper 200, and FIG. The schematic diagram which shows a mode that it is lifted up, touching the buttocks 310 of the person 300. FIG. FIG. 6 is a schematic diagram showing a state in which the dorsal end 22 of the inner pad 100 is turned over toward the buttocks 310 from the state shown in FIG. FIG. 11 is a schematic diagram showing a state in which the inner region 23 that is being worn is turned over toward the buttocks 310 side.

Next, the action of the inner pad 100 of this embodiment will be described. As shown in FIG. 4, the inner pad 100 is used in a state of being superimposed on the inner surface of the underpants-type diaper 200 .

When the wearer 300 of the pants-type diaper 200 to which the inner pad 100 is attached is to excrete in the toilet or to replace the used inner pad 100, the pants-type diaper 200 is lowered to around the knee, and after that, the pants-type diaper 200 is lowered. 200 is pulled up to the wearing position.

When pulling up the pants-type diaper 200, the edge 22a of the back end 22 of the inner pad 100 is pulled up while touching the buttocks 310 of the wearer 300, as shown in FIG. As a result, as shown in FIG. 6, the dorsal end 22 of the inner pad 100 bends toward the buttocks 310 and is caught between the buttocks 310 and turned inside out.

When the pants-type diaper 200 is pulled up while the dorsal end 22 turned up toward the buttocks 310 and the buttocks 310 are in contact with each other, the frictional force generated between the buttocks 310 and the turned-up dorsal end 22 causes The inner region 23 that continues to the dorsal end 22 is also easily rolled up by being caught on the buttocks 310 side.

However, in the inner pad 100 of the present embodiment, as described above, the fastening tape 50 fixed to the inner region 23 having higher rigidity than the dorsal end 22 has an edge 51 which is a boundary where the rigidity against bending is switched. It is arranged so as to match the line L1.

As a result, when the position bent to the buttocks 310 side shifts from the dorsal end 22 with relatively low bending rigidity to the inner region 23 with relatively high bending rigidity, the boundary line L1 is used as a boundary for bending rigidity. is increased, the rigidity against bending of the fastening tape 50 itself and the rigidity against bending due to the joining force between the fastening tape 50 and the top sheet 210 of the pants-type diaper 200 are added.

As a result, in the inner region 23 bounded by the boundary line L1, compared to the dorsal end portion 22, the bending rigidity of the inner pad 100 is greatly increased. Therefore, even when the pants-type diaper 200 is pulled up to the wearing position, the inner pad 100 remains in a state in which only the back end 22 is turned up as shown in FIG. It is possible to prevent or suppress the movement of the position of bending toward the buttocks 310 side to the inner region 23 due to slippage between them. In other words, the inner pad 100 of the present embodiment can prevent the wearing state of the pants-type diaper 200 from changing.

On the other hand, in the inner pad 400 to which the present invention is not applied, as shown in FIG. Instead, it exists in the inner region 23 .

In the pants-type diaper 200 to which the inner pad 400 is attached, when the back end 22 is turned over toward the buttocks 310 and the back end 22 and the buttocks 310 are in contact with each other, the pants-type diaper 200 is pulled up. In the inner region 23 connected to the dorsal end 22, at the boundary line L1, only the presence of the absorbent body 13 increases the rigidity against bending. There is no increase in stiffness against bending due to the bonding force with the top sheet 210 .

Therefore, with the force of the pull-up of the pants-type diaper 200, the bent position toward the buttocks 310 shifts to the inner region 23, bends toward the buttocks 310, and is turned inside out. Then, the pull-up force of the pants-type diaper 200 moves to the portion where the fastening tape 50 is provided, and the fastening tape 50 is peeled off from the top sheet 210 and rolled into the buttocks 310 side. As a result, the wearing state of the underpants-type diaper 200 is changed, and the absorption performance of the absorber 13 is lowered.

The inner pad 100 of the present embodiment has a configuration in which the edge 51 of the fastening tape 50 is aligned with the boundary line L1 where the rigidity is changed from the low-rigidity region to the high-rigidity region. By increasing it, it is possible to prevent the state of the inner pad 100 attached to the pants-type diaper 200 from changing, and to prevent the absorption performance of the absorbent body 13 from deteriorating.

The above description of the inner pad 100 was only for the dorsal side including the dorsal end 22 of the inner pad 100, but the ventral side including the ventral end 21 is the same. An edge 51 of the fastening tape 50 fixed to the inner region 23 having the highest bending rigidity is provided along the boundary line L1 where the bending rigidity is switched.

Therefore, when the portion bent toward the abdomen side transitions from the ventral end portion 21 with relatively low bending rigidity to the inner region 23 with relatively high bending rigidity, the bending rigidity is high with the boundary line L1 as the boundary. At the same time, the bending rigidity of the fastening tape 50 itself is increased, and the bonding force of the fastening tape 50 to the top sheet 210 of the pants-type diaper 200 increases the bending rigidity. can be increased to

As a result, even when the pants-type diaper 200 is pulled up to the wearing position, the inner pad 100 remains in a state in which only the belly end 21 is turned up as shown in FIG. It is possible to prevent or suppress the bending of the inner region 23 toward the lower abdomen side, thereby preventing the wearing state of the pants-type diaper 200 from changing.

In the auxiliary absorbent article according to the present invention, the dorsal region corresponding to the wearer's buttocks may have the above-described configuration, and the ventral region corresponding to the wearer's ventral region may be , may not have the configuration described above.

In the inner pad 100 of this embodiment, the edge 51 of the fastening tape 50 is a boundary line between the inner region 23 where the absorbent body 13 is arranged and the dorsal end 22 and ventral end 21 where the absorbent body 13 is not arranged. Although the fastening tape 50 is provided in line with L1, the auxiliary absorbent article according to the present invention is not limited to this embodiment.

That is, in the auxiliary absorbent article according to the present invention, the fastening member is provided on the side with relatively high bending rigidity at the boundary line where the region with relatively low bending rigidity switches to the high bending rigidity region in the longitudinal direction. are arranged so that their edges coincide with each other.

That is, the auxiliary absorbent article according to the present invention is resistant to bending of the main body of the auxiliary absorbent article (the portion that functions as an absorbent article consisting of the top sheet 11, the absorbent body 13, and the back sheet 12, excluding the fastening tape 50). At the position where the rigidity is increased (boundary line L1), the fastening tape 50 increases the rigidity against bending (increases the rigidity against bending of the fastening tape 50 itself and the fastening tape 50 is joined to the top sheet 210 of the pants-type diaper 200). (Increased rigidity against bending due to the presence of the flexure) It is sufficient that the rigidity against bending is greatly increased at the boundary line L1 by a configuration in which the positions of the two parts are aligned with each other.

(Modification 1)
FIG. 8 is a cross-sectional view corresponding to FIG. 3 showing a part including the dorsal end 22 of an inner pad 500 that is one of the modifications (Modification 1) of the embodiment. In the illustrated inner pad 500, the absorber 13 is formed by laminating two layers of a first absorber 13c and a second absorber 13d in the thickness direction of the inner pad 500. As shown in FIG.

The first absorbent body 13c is formed longer than the second absorbent body 13d in the longitudinal direction L, and only the first absorbent body 13c is arranged in the region adjacent to the back end 22 inside the boundary line L1, Two layers of the first absorbent body 13c and the second absorbent body 13d are arranged in the area inside the boundary line L2 inside the boundary line L1.

The first absorbent body 13c and the second absorbent body 13d may have the same composition or may have different compositions. Further, the first absorbent body 13c and the second absorbent body 13d may have the same thickness, or may have different thicknesses.

In the inner pad 500, the fastening tape 50 is provided in the two-layer region 25 where the two layers of the first absorbent body 13c and the second absorbent body 13d are arranged, and the end on the dorsal end portion 22 side is provided. The edge 51 is arranged so as to coincide with the boundary line L2 between the area where only the first absorbent body 13c is arranged and the two-layer area 25. As shown in FIG.

Here, the boundary line L2 is a boundary line in the longitudinal direction L where the area 24 with relatively low bending rigidity switches to the area with high bending rigidity (two-layer area 25).

In the inner pad 500 of Modification 1 configured in this manner, the edge 51 of the fastening tape 50 fixed to the region 25 with relatively high bending rigidity extends from the region 24 with relatively low bending rigidity. It is arranged so as to match the boundary line L2 where it switches to the high area 25 .

As a result, when the position bent toward the buttocks 310 shifts from the region 24 with relatively low bending rigidity to the region 25 with high bending rigidity, the bending rigidity is switched to high along the boundary line L2. The rigidity against bending of the clothing tape 50 itself and the rigidity due to the joining force between the fastening tape 50 and the top sheet 210 of the pants-type diaper 200 are added.

As a result, in the region 25 on the center side in the longitudinal direction L of the boundary line L2, compared to the region 24 on the end side in the longitudinal direction L, the bending rigidity of the inner pad 500 is greatly increased. Therefore, even if the pants-type diaper 200 is pulled up to the wearing position, the inner pad 500 can prevent or suppress the region 25 from being turned up toward the buttocks 310 while only the region 24 is turned up. It is possible to prevent the worn state of the type diaper 200 from changing.

In Modification 1, of the two layers of absorbent bodies, the longer first absorbent body 13c is arranged on the side closer to the top sheet 11, and the shorter second absorbent body 13d is arranged on the side closer to the back sheet 12. However, the longer first absorbent core 13c may be arranged closer to the back sheet 12, and the shorter second absorbent core 13d may be arranged closer to the top sheet 11. .

However, the inner pad in which the longer first absorbent body 13c is arranged on the side closer to the top sheet 11 has a greater difference in rigidity against bending at the boundary line L2. more preferred.

In Modification 1, the absorbent body 13 is composed of two layers of a first absorbent body 13c and a second absorbent body 13d having different lengths, but the absorbent body 13 is composed of three or more layers. Even if there is, it is equally applicable.

(Modification 2)
FIG. 9 is a cross-sectional view corresponding to FIG. 3 showing a part including the dorsal end 22 of an inner pad 600 that is another modification (modification 2) of the embodiment. In the illustrated inner pad 600, the absorber 13 is formed of a single layer in the thickness direction of the inner pad 600, but in the longitudinal direction L, the area having a relatively small basis weight (low area 13g) is large. portion (high basis weight portion 13h).

Specifically, a low basis weight portion 13g is formed in a portion of the absorbent body 13 near the end portion near the dorsal end portion 22 in the longitudinal direction L, and a region closer to the center in the longitudinal direction L than the low basis weight portion 13g. A high basis weight portion 13h is formed in the .

Note that the material of the absorbent of the low basis weight portion 13g and the material of the absorbent body of the high basis weight portion 13h may be the same or different.

In the inner pad 600, the fixing tape 50 is provided in the region of the high basis weight portion 13h, and the edge 51 on the side of the back end portion 22 is the boundary line between the low basis weight portion 13g and the high basis weight portion 13h. It is arranged to coincide with L3.

Here, since the high basis weight portion 13h has a larger basis weight than the low basis weight portion 13g, the rigidity against bending is relatively high. Therefore, a boundary line L3 dividing the low basis weight portion 13g and the high basis weight portion 13h in the longitudinal direction L serves as a boundary line where the rigidity against bending is switched.

In the inner pad 600 of Modification 2 configured in this way, the edge 51 of the fastening tape 50 fixed to the region 27 with relatively high bending rigidity extends from the region 26 with relatively low bending rigidity. It is arranged so as to coincide with the boundary line L3 where it switches to the high area 27 .

As a result, when the position bent toward the buttocks 310 shifts from the area 26 with relatively low bending rigidity to the area 27 with high bending rigidity, the bending rigidity is switched to high along the boundary line L3. The rigidity against bending of the clothing tape 50 itself and the rigidity against bending due to the joining force between the fastening tape 50 and the top sheet 210 of the pants-type diaper 200 are added.

As a result, the bending rigidity of the inner pad 600 is significantly increased in the region 27 bordering on the boundary line L3 compared to the region 26 . Therefore, even if the pants-type diaper 200 is pulled up to the wearing position, the inner pad 600 can prevent or suppress the region 27 from being turned up toward the buttocks 310 while only the region 26 is turned up. It is possible to prevent the worn state of the type diaper 200 from changing.

In the above-described embodiment and modifications, the difference in bending rigidity between a region (portion) with relatively high bending rigidity and a region (portion) with relatively low bending rigidity is, for example, relatively Preferably, the higher bending stiffness is at least 1.2 times the lower bending stiffness. However, the auxiliary absorbent article according to the present invention is not limited to this difference in rigidity.

Here, an example of the method for measuring the rigidity against bending described above will be described below, taking the inner pad 500 having the two layers of

absorbers

13c and 13d shown in Modification 1 as an example.

The bending rigidity was measured by applying an external force to the end of the inner pad 500 in the longitudinal direction L under the following test conditions using the following torsion tester, and bending the inner pad 500 at a predetermined angle. The stress acting on the inner pad 500 at this time was measured, and the stiffness against bending was evaluated based on the ratio of the measured stress to an arbitrary bending angle (value B in Table 1 below). Therefore, as an evaluation, the higher the ratio value (B value), the higher the rigidity against bending.

(Torsion tester) Large torsion tester KES-YN-1-B (manufactured by Kato Tech)
(Test condition)
・SENS: 2
・Torsion angle: 70 [degree]
・CONTROL: 7
・SPEED: 12
・ Specimen shape: MD × CD = 225 [mm] × 65 [mm]

　The results of the evaluation by the above test are shown in Table 1 below.

In Table 1, "upper layer only" is the region 24 where only the first absorbent body 13c in Modification 1 exists, and "upper and lower layer current" is the region 24 where the first absorbent body 13c and the second absorbent body 13d in Modification 1 exist. This is the area 25 where the As a result of the evaluation, the average B value in the region 24 where only the first absorbent body 13c exists is 11.4, and the average B value in the region 25 where the first absorbent body 13c and the second absorbent body 13d exist. The value was 13.7.

According to this evaluation, the B value (average value) in region 25 was 1.2018 [times] the B value (average value) in region 24. Therefore, it can be evaluated that in the inner pad 500 having a rigidity difference (ratio) with respect to bending of 1.2 [times] or more, the region 25 is not caught on the buttocks 310 side.

The evaluation of the stiffness difference described above is an example, and in the auxiliary absorbent article according to the present invention, the stiffness difference is not limited to the one evaluated in the above evaluation. It is not limited to 1.2 [times] or more.
